Description

Technical Field

[0001] This utility model relates to the technical field of gas extinguishing test experiments, specifically to a gas extinguishing test system. Background Technology

[0002] When conducting extinguishing tests and concentration distribution tests on Class A and Class B fires using gaseous fire suppression systems, it is necessary to manually ignite the burning material.

Manual ignition carries certain risks; improper operation can easily cause burns, and manual ignition is also highly inconsistent. Common exhaust pipes are usually located in the upper middle part, which hinders exhaust gas discharge. Conventional testing equipment typically uses a method of weighing the extinguishing agent tanks separately after the experiment and then calculating the total extinguishing agent consumption, which has certain measurement errors and is time-consuming.
